[0002] Focused ultrasound uses the principles of ultrasound directionality, tissue penetration and focusing to gather ultrasound waves that penetrate tissues and release a large amount of energy in the focused area, with good penetration and positioning. Existing focused ultrasound treatment handles can accurately position ultrasound energy in target treatment tissues, such as the dermis, subcutaneous fat layer, SMAS layer, etc., to achieve lifting, firming, skin rejuvenation and fat reduction effects.

[0003] Some current ultrasonic therapeutic devices usually consist of a handle and a treatment head, wherein the transducer in the treatment head can emit ultrasonic waves. The ultrasonic waves emitted by common ultrasonic therapeutic devices hit the skin tissue in a dot-like manner.

[0023] See also Figure 1 As shown, the intelligent ultrasonic treatment device of the utility model comprises: a housing 1, a first drive device 2, a second drive device 3 and a transducer 4. The housing 1 is provided with a mounting cavity 10. The first drive device 2, the second drive device 3 and the transducer 4 are all arranged in the housing 1. The first drive device 2 comprises a motor 21 and a transmission rod 22. The output shaft of the motor 21 is coaxially fixedly connected with the transmission rod 22, such as threaded connection, welding or integral molding, so as to improve the connection strength and coaxiality between the transmission rod 22 and the output shaft of the motor 21. The second drive device 3 is connected to the transmission rod 22. The second drive device 3 comprises an electromagnetic drive assembly 31, a spring 32 and a magnetic member 33. The spring 32 is arranged between the electromagnetic drive assembly 31 and the magnetic member 33. The transducer 4 is fixedly connected with the magnetic member 33.

[0024] The electromagnetic drive assembly 31 may be an electromagnetic device that can generate electromagnetic force when powered on and loses electromagnetic force when powered off, such as an electromagnet or an electromagnetic chuck. The magnetic component 33 may be a paramagnetic component that can be attracted and repelled by electromagnetic force, such as a permanent magnet with magnetic poles (N pole and S pole), or a paramagnetic component that can only be attracted by electromagnetic force, such as a ferromagnet. The type of the magnetic component 33 may be selected according to the specific application scenario.

[0025] The motor 21 drives the transmission rod 22 to perform linear motion along the X axis, so that the transmission rod 22 drives the second drive device 3 and the transducer 4 to perform linear motion along the X axis as a whole, thereby realizing the lateral movement of the focus of the transducer 4. When the electromagnetic drive assembly 31 is energized, it generates electromagnetic force and attracts or repels the magnetic member 33, so as to drive the magnetic member 33 to overcome the elastic force of the spring 32 to perform linear motion along the Y axis, and the magnetic member 33 synchronously performs linear motion along the Y axis with the transducer 4. When the force between the electromagnetic drive assembly 31 and the magnetic member 33 and the elastic force generated during the deformation (compression deformation or tensile deformation) of the spring 32 are balanced, the transducer 4 will remain stationary at a certain position in the Y axis direction to obtain the desired focal position. By controlling the magnitude of the electromagnetic force generated by the electromagnetic drive assembly 31, the force between the electromagnetic drive assembly 31 and the magnetic member 33 and the elastic force generated by the spring 32 under different deformation states can be balanced, so that the transducer 4 remains stationary at different positions in the Y axis direction, thereby realizing the longitudinal adjustment of the focus of the transducer 4.

[0026] The second driving device 3 also includes a mounting frame, which includes a fixed part and a movable part 342. The movable part 342 can reciprocate relative to the fixed part.

[0027] Specifically, the fixed part includes a sleeve 341, the axis of the sleeve 341 is arranged along the Y-axis direction, the electromagnetic drive assembly 31, the spring 32 and the moving part 342 are all arranged in the sleeve 341, and the moving part 342 can be a moving block that contacts and cooperates with the inner wall of the sleeve 341 or a cylindrical structure that cooperates with the inner wall of the sleeve 341, which can ensure that the moving part 342 can reliably move freely in the sleeve 341. The magnetic part 33 and the transducer 4 are both fixed on the moving part 342.

[0028] The motor 21 drives the transmission rod 22 to perform linear motion along the X-axis, so that the transmission rod 22 drives the sleeve 341, the moving part 342 and the transducer 4 to perform linear motion along the X-axis as a whole, thereby realizing the lateral movement of the focus of the transducer 4. When the electromagnetic drive assembly 31 is energized, it generates an electromagnetic force, so that the electromagnetic drive assembly 31 and the magnetic member 33 are attracted or repelled to overcome the elastic force of the spring 32, thereby driving the moving part 342 and the transducer 4 to perform linear motion along the Y-axis direction as a whole in the sleeve 341.

[0029] The fixed part also includes a connecting piece 343 and a first guide rod 344 arranged along the Y-axis direction. The upper end of the first guide rod 344 is fixedly connected to the connecting piece 343. The connecting piece 343 is fixedly connected to the transmission rod 22. The sleeve 341 is installed on the connecting piece 343 and is located inside the first guide rod 344.

The magnetic part 33 and the transducer 4 are both fixed on the moving part 342.

[0030] The motor 21 drives the transmission rod 22 to perform linear motion along the X-axis, so that the transmission rod 22 drives the first guide rod 344, the moving part 342 and the transducer 4 to perform linear motion along the X-axis as a whole, thereby realizing the lateral movement of the focus of the transducer 4. The electromagnetic drive assembly 31 generates electromagnetic force when energized, so that the electromagnetic drive assembly 31 and the magnetic member 33 are attracted or repelled to overcome the elastic force of the spring 32, thereby driving the moving part 342 and the transducer 4 to perform linear motion along the Y-axis on the first guide rod 344.

[0031] The first driving device 2 further includes a second guide rod arranged in parallel on both sides of the transmission rod 22, the two ends of the second guide rod are respectively fixed on the side walls of the inner shell 6, and a second guide hole is provided on the fixed part, and the second guide rod is inserted into the second guide hole. The function of the second guide rod is to bear the overall weight of the second driving device 3 and the transducer 4, to prevent the weight of the second driving device 3 and the transducer 4 from being shared and applied to the transmission rod 22, causing the transmission rod 22 to bend and deform, thereby increasing the load of the motor 21, and to guide the lateral movement of the second driving device 3 and the transducer 4, thereby improving the stability of the lateral movement of the second driving device 3 and the transducer 4.

[0032] An inner shell 5 is provided in the shell 1. The inner shell 5 is provided with a sealed accommodating chamber 50. The accommodating chamber 50 is filled with a conducting liquid. The transmission rod 22 is transversely arranged in the inner shell 5. A waterproof telescopic sleeve 7 is sleeved on the transmission rod 22 to prevent the conducting liquid from contacting the transmission rod 22. The transducer 4 and the second driving device 3 are both arranged in the inner shell 5. A first sound-transmitting opening 13 arranged along the X-axis direction is provided at the bottom of the shell 1. A second sound-transmitting opening 51 arranged along the X-axis direction is provided at a position of the inner shell 5 facing the first sound-transmitting opening 13. The second sound-transmitting opening 51 is sealed and covered with a sound-transmitting membrane 52. The emitting surface of the transducer 4 faces the second sound-transmitting opening 51. The projection area of ​​the second sound-transmitting opening 51 covers the transverse moving track of the focus of the transducer 4. The energy emitted by the transducer 4 can penetrate the second sound-transmitting opening 51 and act on the tissue to be treated.

[0033] The housing 1 includes a gripping portion 11 and a treatment portion 12. The gripping portion 11 and the treatment portion 12 are arranged at an angle, for example, substantially at a right angle, that is, the gripping portion 11 is substantially arranged in the X-axis direction, and the treatment portion 12 is substantially arranged in the Y-axis direction.

The inner housing 5 is disposed in the second mounting cavity 102, and the first driving device 2 is disposed in the first mounting cavity 101.

[0034] A pressure balancing device 6 is also provided in the accommodating chamber 50 to balance the pressure fluctuations in the accommodating chamber 50 caused by the movement of the transducer 4. The pressure balancing device 6 includes a retractable airbag 61. The side wall of the retractable airbag 61 is in the shape of a bellows as a whole, so it has good deformation ability. The retractable airbag 61 is provided with a connection port, and the inner side wall of the inner shell 5 is provided with a mounting platform 62. The connection port is sealed and sleeved on the mounting platform 62. The mounting platform 62 is provided with a vent hole 63 to connect the inner cavity of the retractable airbag 61 with the outside. When the transducer 4 moves in the accommodating chamber 50, the pressure in the accommodating chamber 50 changes. Since the volume of the retractable airbag 61 can be changed, the retractable airbag 61 dynamically compensates for the pressure change in the accommodating chamber 50 by adaptively changing its own volume, thereby achieving the purpose of balancing the pressure in the accommodating chamber 50.
